FLUID on wATEa .mcxn'r CONNECTION.

To all whom 'it may concern:

Be it known that I, FRITZ WILHELM- SCHROEDER, a subject of the King of Denmark, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a new and useful Fluid or Water Jacket Connection, of which the following is a specification.

'My invention relates to improvements in fluid connections between the rotating and stationary] ar'tsiof machinery generally, and is herein s own for the sake of illustration and description as embodied in an air compressor of the rotary type.

The object of myinvention is to provide a novel, simple and efficient means for conveye ing fluid between the moving and stationary parts of machines, particularly between the stationary portion ,or frame and the rotating portion or cylinder structure of an air compressor of the rotary type, when my invention is embodied in such a mechanism.

The various advantages .obtained by the use of my invention will be fully and clearly ap arent from the description herein given.

11 the drawings Figure 1 is a longitudinal section of an air, compressor provided with my invention; Fig. 2 an enlarged longitudinal section of a portion of the mechanism Fig. 9, a view similar toFig. 2,

taken in a plane half way between the cylinders of the compressor; Figs. 3, 4, 5, 6, 7 and 8, detail'views of the connecting mechanism;

but illustrating a modification, and Figs. 10 and 11, detall views of the connecting mechanism as adapted in Fig. 9.

For "the purpose of fully explaining the nature of my invention and illustrating one exem lification or embodiment thereof in a' comp ete operative mechanism I have chosen to illustrate and describe it in connection with and embodied in an air compressor of the rotary type, in which the cyhnders are mounted on and rotate with a shaft, the

shaft being borne by suitable bearings in a stationary frame, the cylinders being cored, to furnisha water jacket for the purpose of cooling the same. The compressor obvi ousl y may be connected to or operated by any source of power, as an electric motor, steam engine or the like. It will be understood, further, that with proper'mechanical changes my invention is applicable to other machines with the same results as are accomplished when used in-connection withan Specification of LettersPatent.

air compressor, as herein il ustrated and described. Consequently, I contemplate using my invention wherever applicable.

The preferred form and arrangement of my mechanism is illustrated in the drawings;

In Fig. 1 the rotating ortion of the compressor is made up of a p urality of cylinders 1 radially mounted on a shaft 2, the shaft being-carried by suitable bearings 2"in the case or frame 3. Eccentric bearings 4 carried by or a part of the case 3 serve as bearing surfaces on which suitable piston suspending devices 4 rotate. A suitable valve 17 at tached to the frame 3 is operative within the shaft 2 to supply and exhaust the air to and from the cylinders. Within eccentric bearings/i or frame 3 are formed suitable cavities 5 and 5' which are provided with suitable connections 6 and 6 to which connections are attached the source offiuid supply and discharge respectively. I

Mounted on the inner face of each eccentrio bearing 4-that is, the face opposed to 4,

the-rotating part, and concentric with the axis of rotation of the rotating portion of the mechanism, is a part 7,. which is provided This part 7, which may be of any suitable form, is shown in the drawings as a ring or annulus of V shaped cross-section, with the hollow. or groove side toward the rotating part. J This ring 7 is mounted on the bearing 4 by suitable su ports or pin-s 9 and 9, some of which are hol ow to form fluid conduits, as shown in Figs. 1 and 5, and communicate with cavity 1 5. Suitable holes 20 in ring 7' permit the entrance of the extremities of pins 9 arid 9, a

fluid tight joint between said ring and each pin being maintained by any'common or ordinary form of packing, as by packing disks 11, metal washers 12 and elastic material 13. This elastic material, such as spring 13, which 'I prefer to have carried by the in, is inserted between the face of ring 7 or isk 1 1 and the face of, eccentric bearing 4. This spring tends to keep ring 7 in close contact with the face of the rotating portion of the device and also ,to keepa tight joint between the packing disk, the pin, washer and the I preferably provide an annular recess 16 on each side of the rotating part in which ring 7 is operative.

A suitable number of holes or ports 8 are provided in the face of" the rotating art 1 which communicate with a fluid cormg 15 i into cavity 5.

witli'n part i be of such shape as to describe a path withm the limits a-c of the annular groove 7" 1n ring 7.

Fluid may now enter through either one of;

the connections 6 and 6say connection 6,

1. These holes or'ports 8 must It then passes through hollow pins 9"into groove 7 of ring 7, thence I *through ports 8 into the coring 15,'thence out through port 8 on the other side of the rotating part into groove 7 of the ring 7 through t e hollow pins 9 into the cavity 5' in the stationary art on that side of the mechanism. The uid then escapes through connection. 6.

As shown in the drawings,-the connecting construction above described is 1n duplicate;

'that is, the fluid connecting device on one side of the mechanism is identical with that on the other side, so that either sidewill act as the admission portion and the otheras the exit portion. Itfollows that regardless of the rotation of the moving portlon of the mechanism, fluid supplied at connection 6 or 6 is free to flow through the stationary portion into and through the rotating pdrtion and out through the corresponding course rovided on the opposite side of the mechanism, a fluid tight joint being maintained at all times between both portions.

It is apparent-that the part 7 which is shown as mounted .on the stationary portion of-the mechanism can be equally well mount-- ed in a similar or equivalent manner on the rotating portion. The operation of the device with such mounting of part 7 will be identical with that heretofore described.

It is obviously within the scope of the in- I vention to employ, instead of part 7 having one annular groove, a-part having two annu-' lar grooves so that the crosssection would I be W shaped. Such a structure couldbe apthe opposing face of the frame.

plied to either side of the rotating part and Figs. 9, 10 and 11 illustrate this-modification. In this modification. cavity 5 must be subdivided into compartments 5 and 5 and these compartments should have suitable connections 6 and 6' respectively for inlet and outlet of fluid. Ring 7 is provided with two annular grooves 7 and 7 Each groove is provided with suitable holes 21 which permit the entrance of pins 9, 9 9 and 9, pins 9" and 9* being hollow and in communication with grooves 7 and 7 and compartments 5 and 5 respectively. In all other respects the construction of the rin' pins and means for holding the same fluid tight on the rotatin part is ldentical with the arrange.- ment eretofore described. Passages or ports Sand 8" leading to the coring 15 within "the rotating portion of the mechanism are ceases one of the connections 6", 6-say connection 6", passes into the compartment 5, thence through hollow pins 9" into groove 7" thence through port 8 into the coring 15, thence out through port 8 into groove 7" through hollow pins 9 into compartment 5, thence out through connection 6". nection 6 is used for inlet of fluid the action or procedure of the fluid through the mechanism is in'the reverse manner. This operation is true, no matter'in which direction the rotating part revolves. It is apparent that in the latter modification ring 7could as well be mounted on the rotating part as on the stationary art and either construction be equally wit llll the scope of the invention.

As hereinbeforc referred to, the machine herein shown and described is here sclected as best illustrating my invention, and eonsequently my lnventlon is not llIIlltGCt to any special features thereof not directly concerned, inasmuchas various fmechamcal changes might be made without departing from the spirit and scope of my invention and claims.
